Kaplan turbine tip vortex cavitation is a well-known phenomenon that im-pacts the performance of large-diameter turbines. This phenomenon is associated with high levels of structural vibration that can severely affected the structural integrity of such turbines. Severe metal erosion and high levels of sound and structural fatigue are among the major adverse manifestation of flow induced vibration. Mechanical erosion due to cavitation occurs at the tip end of the runner blades on the suction side and the discharge seal. In this work a review of the current mitigation techniques is explored and discussed. Air injection is one of the well-known approaches in this area and this study explore the benefit of using such techniques in Haditha hydropower plant in Iraq. Haditha plant is the second largest hydropower plant in Iraq which suffer from severe mechanical erosion and component degradation due to cavitation related issues. It had been reported that air injection has the potential to mitigates the adverse effect caused by cavitation.
